Friendship and consumption networks in adolescents and their relationship to stress and cannabis use intention

Background: Cannabis is an illegal psychoactive substance that’s use is widespread among adolescents. During adolescence, many changes can cause stress. In this phase, the group of friends becomes increasingly important, being a situation of vulnerability for the beginning of cannabis use, either as an escape mechanism or due to peer’s influence. Therefore, the purpose of this study is to describe and analyze the structure of the consumption and friendship network, the intention to use cannabis, and the stress in a secondary school class. Methods: An online platform with validated self-reported questionnaires were used for data collection. Results: The sample consisted of adolescents (n = 20) aged 14–16 from a third-year class of compulsory secondary education in Ponferrada (León, Spain). Significant differences were obtained concerning consumption intention and the different network metrics in both the friendship and consumption networks. Subsequently, the representation of these networks was carried out. Conclusions: Social Network Analysis is a very useful tool that provides a picture of the context in which adolescents are located. In the consumption network, there are central actors who have not yet consumed cannabis; this is a crucial moment to implement prevention strategies

Implementation of COIL in mental health education: Outcomes of a collaboration between Spain and the United States nursing students

Collaborative International Online Learning (COIL) provides students meaningful and valuable engagement with students in another country to reach the goals of academic programs at the participating institutions. The strategy has demonstrated benefits for nursing students, including the acquisition of self-awareness, empathy, cultural humility, and leadership skills. The aim of this study was to share the results of the partnership in a COIL project using digital technology between a university in the United States and a university in Spain. The goals of this collaboration were twofold: to expose students in the U.S. and Spain to an international experience on mental health and to provide a comparative view of their respective health care systems. The chosen technique focuses on perceptions of mental health and how mental health care is delivered in clinical settings. A total of 166 students took part in this experience. The virtual exchange allowed students and faculty to share best practices in caring for people with mental illness. Nursing students providing care to COVID-19 patients reflected on lessons learned during the pandemic and its impact on community mental health. Small group activities such as icebreakers, homework assignments, and reflections were used to share and compare experiences. Students completed COIL surveys, which demonstrated that students from both countries perceived learning gains using evidence-based best practices related to key nursing concepts in a mutually respectful virtual exchange. The results show a perceived increase in the comprehension of mental health-related content and enhancement of clinical practice. Therefore, the COIL methodology is a feasible option as it allows for an intercultural exchange with an in-depth examination of content from the learners and teaching perspectives. In addition, it prepares students to work in international teams virtually.S

Terahertz-based system for dehydration analysis of hydrogel contact lenses

The use of terahertz-based techniques has grown very fast since they are capable of performingevaluations at molecular level, being very suitable for the analysis of biological samples and bioma-terials such as those for contact lenses. These biomaterials are continuously evolving to enhancethe lens wearer’s comfort by improving their hydration state and surface wettability. Therefore, thisstudy examines a novel terahertz system for the assessment of the temporary in vitro dehydrationof hydrogel contact lenses, which provides a new index to assess their state of hydration. Severalconventional and silicone hydrogel contact lenses and lens care solutions were analysed. Traditionalmethods such as the gravimetric determination of water content and the measurement of the staticcontact angle were also carried out for the validation of the developed system. The dehydrationrate measurements of contact lenses obtained with the proposed system correlated with the valuesprovided by traditional methods. As a whole, conventional hydrogel contact lenses exhibited thelowest values for dehydration rate. The tests conducted on various solutions showed a correlationbetween the wetting action of the solution and the dehydration rate of the contact lens material.Peer ReviewedPostprint (published version

Fashion influencers and Instagram. A quasi-perfect binomial

Influencers, thanks to their ability to connect with the public, have revolutionized brand communication making it less invasive and at the same time attractive and dynamic. This research explores the behavior followed by the main Spanish fashion followers, focusing on the strategies and resources used in their communication through Instagram profiles. The gradual incorporation of men into this sector requires identifying whether the publication of habits in this social network vary or not with respect to the author’s gender. In addition, compliance with Spanish legislation on advertising is monitored, which obliges the authors to explicitly indicate any message that promotes a product or service from a contractual agreement

The Impact of the COVID-19 Pandemic on Self-Harm Attempts Observed in a Hospital Emergency Department

Suicide is a significant public health concern, with one million lives lost to it every year. Suicidal ideation and attempts are markers of high risk. The COVID-19 pandemic has had a negative psychological impact on the population. This study aims to describe and analyze the clinical and sociodemographic characteristics of patients who have received medical attention for self-harm attempts in a hospital emergency department, comparing the period before and after the COVID-19 pandemic. This is a descriptive, retrospective study that collected data from medical records of patients who received care for self-harm attempts in the emergency department. The data included cases from 1 January 2018 to 31 December 2022. In total, 529 cases of self-harm attempts were identified, of which 62.8% were female. The number of post-pandemic self-harm attempts significantly increased compared to the period before the pandemic. The most used method for self-harm was medication ingestion. This study revealed that over one-third of the participants had previously attempted suicide. Most self-harm attempts were made by women in the 10–20 or 41–50 age groups, with a history of psychiatric illness and multiple medications. The study results also highlighted an increase in self-harm attempts during the COVID-19 pandemic.SIThis research received no external fundin

Luces y sombras para la salud pública: análisis crítico de la legislación sobre el tabaco en España

Tobacco smoking is a chronic disease that is the leading preventable cause of death in developed countries. In Spain, the prevalence of tobacco use has decreased driven by the implementation of tobacco control policies; however, current legislation does not establish a harmonized regulation for all tobacco products. The aim of this article is to review the current legislation and critically analyze its limitations in relation to the principles of good administration now defined in the Law 39/2015. Spanish in force tobacco control policies main limitations can be divided into four areas: the lack of specific regulation for new tobacco products; the differences in their regulation; the lack of information to the general population on their harmful effects and the new developments in the regulation of smoke-free spaces; and the lack of adaptation of the regulation to the most recent scientific evidence. All in all, the quality of tobacco control regulations in Spain, despite the successes achieved with the Law 28/2005, has been compromised by the State's laxity in the legislative, regulatory, and administrative spheres, which has led to a regulatory stagnation that runs counter to the principles of good regulation. This review should encourage scientific organizations and civil society associations to call for an actualization of the tobacco legislation, with determined and coordinated prevention and control policies to promote a tobacco-free Spain.

Self perceived health and stress in the pregnancy during the COVID-19 pandemic

[EN] Introduction. The COVID-19 pandemic has had numerous maternal and neonatal consequences, especially at the mental level. Pregnant women experience a rise in anxiety symptoms and prenatal stress. Aims: The aim was to describe self-perceived health status, general stress and prenatal stress and to analyze relations and associations with sociodemographic factors. Methods: A quantitative, descriptive and cross-sectional study was conducted using non-probabilistic circumstantial sampling. The sample was recruited during the first trimester of pregnancy during the control obstetrical visit. The Google Forms platform was used. A total of 297 women participated in the study. The Prenatal Distress Questionnaire (PDQ), the Perceived Stress Score (PSS) and the General Health Questionnaire (GHQ-28) were used. Results: Primiparas presented higher levels of worry about childbirth and the baby (10.93 ± 4.73) than multiparous women (9.88 ± 3.96). Somatic symptoms were present in 6% of the women. Anxiety-insomnia was scored positively by 18% of the women. In the Spearman correlation analysis, statistically significant values were found between almost all study variables. A positive correlation was observed between self-perceived health and prenatal and general stress levels. Discussion: During the first trimester of gestation, prenatal concerns increase when levels of anxiety, insomnia and depression also increase. There is a clear relationship between prenatal worries, anxiety, insomnia and depression with stress. Health education that focuses on mental health of pregnant women would help reduce worries during pregnancy and would improve the pregnant women perception of her health and well-being.S

Double aortic arch diagnosed in a 44-year-old woman with recurring respiratory infections

Complete vascular rings are originated because of the persistence of the fourth aortic arches, which surround the trachea and esophagus partially or completely, compressing them. The most common type of complete vascular ring is the double aortic arch. Symptoms usually appear in the first months of life, and are provoked by esophageal and tracheal compression. The diagnosis is usually made through the chest X-ray and the esophagogram in patients with dysphagia. We present a case in which the diagnosis of a double aortic arch was made in adulthood, suspected through a spirometry test and a chest X-ray
